ITER is planning to do its flagship D+T runs in 2035, not 2050.

While inertial confinement fusion facilities like NIF are also used for weapons work, the physics of magnetic confinement fusion plasmas are quite different from the physics needed for bombs. There's no chain reaction, and the 'hot neutron physics' is actually a very small part of the overall system. The neutrons essentially go in a straight line until they hit the wall; they don't interact with the plasma itself.

Most people in magnetic confinement fusion are studying magnetized plasma waves, instabilities, turbulence, and other collective behavior that are in a very different regime from bomb physics.
